Specification of Letters Patent.

Application filed September 22, 1921. Serial No. 502,312.

To aZZ whom it may concern:

Be it known that I, MICHAEL DYKAs, a citizen of Poland, residing atChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Aeroplane Toys, of which thefollowing is a specification.

This invention relates to certain new and useful improvements inaeroplane toys and has particular reference to a toy constructed insimulation of an aeroplane or flying machine and containing a springmotor for operating horizontal and perpendicular propeller blades.

The primary object of the invention resides in the provision of anaeroplane toy embodying a spring motor for operating perpendicular andhorizontally disposed ,propeller blades with a cord operated catchdev1ce for the spring motor to control operation thereof and a holdingcord for the toy while suspended in the air.

lVith the above general objects in view and others that will appear asthe nature of the invention is better understood, the invention consistsin the novel form, combination and arrangement of parts hereinafter morefully described in connection with the accompanying drawings and inwhich like characters of reference indicate corresponding partsthroughout the several views.

In the drawings,

Figure l is a top plan view of an aeroplane toy constructed inaccordance with the present invention, showing the catch cord for thespring motor and the holding cord for the toy, with the horizontallydisposed propellers for raising the toy journaled rearwardly of the sidewings and partially overlying the same,

Figure 2 is a horizontal sectional view taken online IIII of Figure 5showing the spring motor and gearing for operating the propeller blades,

Figures 3 and 4 show diagrammatic plan views of the catch device forcontrolling the spring motor, Figure 3 showing the catch device inoperation, and Figure 4 showing the same disengaged from the springmotor,

Figure 5 is a detail sectional view taken on line VV of Figure 1, 1

Figure 6 is a top plan view of a modified form of the toy showing thehorizontally disposed propellers positioned abovethe side wings, and

Figure 7 is another modified form of the toy showing a singlehorizontally disposed propeller centrally positioned above the aeroplanebody or fuselage.

Referring more in detail to the accompanying drawings and in particularto Figures 1 to 5, there is illustrated an aeroplane toy embodying acentral body or fuselage 1 carrying upper and lower planes 2 and 3 andhaving guiding vanes 4 at the rear end of the fuselage.

The propelling means for the toy includes a perpendicular shaft 5.journaled at its upper end in the upper wall. of the fuselage 1 andhaving a key portion 6 upon the u per projecting end thereof, the lowerend 0 the shaft 5 being fixed in a bearing 7 journaled in the lower wallof the fuselage and provided upon the lower projecting end thereof witha horizontally disposed gear 8. A bevel gear 9 is fixed to the shaft 5within the fuselage while a coil band spring 10 is secured at its innerend as at 11 to said shaft while the outer end thereof is secured as at12 to a post 13 depending from the upper wall of the fuselage as clearlyshown in Figures 2 and 5.

A shaft 14 journaled horizontally in the fuselage 1 carries a bevelpinion 15'upon the inner end for engagement with the bevel gear 9 uponthe shaft 5,-the perpendicular propeller 16 being secured to the forwardend of the shaft 14 outwardly of the fuselage 1.

A horizontally disposed propeller is positioned at each side of thefuselage 1, each propellerl? journaled rearwardly and upwardly of theside wings 2 and 3 being fixed to a shaft 18 journaled in rearextensions 19 of the planes 2 and 3 and carrying abevel gear 20 adjacentthe lower end thereof. A horizontal shaft 21 journaled at its outer endin a bracket 22 supported on the lower wing 3 and journaled at its innerend in the adjacent side wall of the fuselage 1 carries a bevel gear 23meshing with the bevel gear 20 upon the shaft 18 while a bevel pinion 24secured to the inner end of the shaft 21 is in mesh with the bevel gear9.

A catch device is associated with the spring motor, the same being shownmore clearly in Figures 3 to 5 and embod ing spaced hangers 25 and 26depending rom the fuselage 1 and through which hangers a catch rod 27 isslidabl mounted, a coil.

spring 28 surrounding t e catch rod between the stop washer 29 and thehanger 26 Patented Jan. 17, 1922.

normally to force the catch rod in a direction toward the gear 8 asshown in Figure 3. When the catch rod 27 is retracted against thetension of the spring by the catch cord 30, the lug 31 upon the catchrod engages the hanger 26 to hold the-catch rod retracted against thetension of the spring as shown in Figure 4.

' In the operation of the device, a key 32 as shown in Figure 1 isemployed for rotating the shaft 5 'to place the spring 10 under tension,and with the catch rod .27 retracted to the position shown in Figure 4,the perpendicular propeller 16 is rotated for forwardly propelling thetoy while the horizontally disposed propellers 17 are similarly rotatedfor elevating the toy, a holding cord 33 attached to the bottom of thefuselage as shown in Figures 1, 3, and 4 being emplo ed for holding thetoy against escape. ith the spring 10 operating the propellers, the toymay be suspended in the air while the spring is under tension, butshould it be desired to retract the toy, the catch cord 30 is operatedto disengage the lug 31 from the hanger 26 and permit the catch rod'27to engage the teeth of the gear 8 as shown in Figure 2 arrestingmovement of the propeller blades while the complete toy is thencontrolled by the holding cord 33.

It will be noted that the longitudinal axis of the catch rod 27 is at anangle to the longitudinal axis of the fuselage 1, so that by pulling thecord 30 the catch rod 27 is shifted slightly laterally through theenlarged opening in the hanger 26 to insure disengagement of the catchrod lug 31 from the hanger. i

y A modified form of the toy is shown in Figure 6 wherein thehorizontally disposed propeller blades 17 are dis osed directly abovethe upper wings 2, whi e in Fi ure 7 another modified form isillustrated "w erein a single horizontally disposed propeller blade 17"is journaled above the fuselage body.

From the above detailed description of the device, it is believed thatthe construction.a nd operation thereof will at once be apparent andwhile there are herein shown and described the preferred embodiments ofthe invention, it is to be understood that minor changes may be madetherein without departing from the spirit and scope of the invention asclaimed.

What is claimed as new is:

1. An aeroplane toy of the type described comprising a central body,lateral win s carried thereby, a shaft journaled in sald body, a bevelgear fixed to said shaft within the body and a gear wheel fixed to saidshaft beneath the body, horizontal shafts journaled on said body andwings, bevel pinions carried by the inner ends of the horizontal shaftsin mesh with said bevel gear,.a band spring associated with saidperpendicular shaft and bevel gear, a perpendicular shaft journaled atopposite sides of the body, a horizontal pro eller journ'aled on theupper end of each side shaft, gear connections between the side shaftsand the horizontal shafts and means associated with the gear carried bythe, lower end of the first named shaft for controlling movementthereof.

2. An aeroplane toy of the type described comprising a central body,lateral wings carried thereby, a shaft journaled in said body, a bevelgear fixed to said shaft within the body and a gear wheel fixed to saidshaft beneath the body, horizontal shafts journaled on said body andwings, bevel pinions carried'by the inner ends of the horizontal shaftsin mesh with said bevel gear, a band spring associated with saidperpendicular shaft and bevel gear, a perpendicular shaft journaledatopposite sides of the body, a horizontal propeller journaled on theupper end of each side shaft, gear connections between the side shaftsand the horizontal shafts, and a tensioned catch rod associated with thegears secured to the lower end of the first named shaft for controllingmovement thereof.

In testimony whereof I aflix my signature.

MICHAEL DYKAS.
